FIELD: power engineering. ^ SUBSTANCE: proposed machine can be used as engine, pump or compressor. Machine has crankcase, cylinder with piston and rod, two crankshafts rotating in opposite directions. Inner space of piston communicates with through axial channel of rod installed in crankcase for reciprocating in suction branch pipe. Rod channel is provided with diffuser from side of piston space, and with contraction from side of suction branch pipe. Delivery valves are installed on cylinder cover, and suction valves, on front wall of piston. Rod and connecting rods of crankshafts are hinge-connected with crossmember. ^ EFFECT: reduced dead space and hydraulic losses. ^ 5 cl, 2 dwg |
